On September 28-29, 2009, the Cascadia Region Earthquake Workgroup (CREW) held the first regional workshop that addressed tsunami vertical evacuation as a new means to protect people and improve community recovery. The two-day workshop included field visits and meetings in Cannon Beach and Seaside, Oregon (September 28), and a workshop in Portland, Oregon (September 29). The event was sponsored by CREW, City of Cannon Beach, Oregon Department of Land Conservation and Development, American Society of Civil Engineers (ASCE), Oregon Emergency Management (OEM), Oregon Department of Geology and Mineral Industries (DOGAMI), and the Western States Seismic Policy Council (WSSPC).
The workshop was designed to encourage discussion between experts and stakeholders about the need for vertical-evacuation options in areas prone to tsunami inundation from a Cascadia subduction zone earthquake.
